IIRC, the purpose of the tape is to force the threads together more

How would possibly physically do that being so soft as compared to metal?

it acts to reduce friction, thus allowing more torque to be applied to the
joint, thus allowing it to be tighter.

What it does is simply fill voids as does pipe dope in a more convenient
form factor...
